Self-Adhesive Waterproof Board

Self-adhesive waterproofing board are common geosynthetic materials in the engineering and environmental protection, featuring waterproofing, tensile-resistance and easy processing. Its self-adhesive layer ensures compatibility with construction in complex environments.

Our self-adhesive waterproof board is extensively applied to tunnel lining structures for wall surface seepage control, significantly reducing construction costs, streamlining installation procedures and accelerating project timelines.

Raw Materials: EVA

Packing Method: Bagged Rolls

Characteristics of Product

  1. Rigorous Product Control

    The production process of self-adhesive waterproof board requires an additional secondary process to apply the adhesive layer. Therefore, we strictly control surface treatment, coating methods, drying, curing and inspection procedures to ensure the qualified process.

    Stable Material Performance

    Self-adhesive waterproof board uses the same base layer as our conventional waterproof board. This offers excellent waterproofing, impermeability, and resistance to environmental stress cracking. Combined with the secondary adhesive layer, the self-adhesive waterproof board retains these inherent properties of the raw material while maintaining its self-adhesive capability.

    Adaptability to Complex Scenarios

    The adhesive surface of self-adhesive waterproof board can bond to most surfaces directly like vertical sidewalls and overhead positions. When we meet some limited situations for large construction machines, where effective anchoring points are also unavailable such as highway or subway tunnels. Our self-adhesive waterproof board effectively achieves reliable waterproofing and impermeability.

Self-adhesive Waterproof Borad Guidelines

  1. Substrate Requirements:

The waterproofing substrate must be structurally sound and level, free from protruding sharp edges, surface pits and dusting. The surface must be clean and dry, with all transitions formed into 50mm-radius arcs. The substrate moisture content must exhibit no visible moisture.


  1. Operation Sequence:

（1） Substrate Surface Cleaning & Repair

（2）Application of Compatible Primer

（3）Application of Compatible Primer

（4）Positioning & Baseline Marking

（5）Installation of Self-adhesive Waterproof Membrane

（6）Roller Compaction & Air Expulsion

（7）Edge Sealing & Overlapping

（8）Inspection & Acceptance

（9）Protective Layer Construction


  2. Installation Details:
  3. On horizonal surfaces:        From the farthest point inward
  4. On vertical surfaces:           Top-down
  5. Wall-to-Floor Transitions:  50mm-radius arcs surface for structural transition
